To all whom it may-concern:

:Be it known" that I, BERNI-IARDT M. GAT- TER'MEIR, a "citizen of the'United States, and

a resident of California, in the county of Monite'au and State ofMissouri, have invented certain new 'and' useiul Improve, ments inGas-Pressure Regulators, of which the following is a specification.

My invention relates to means for automatically controlling the supplyofgas in the degree of use and is an improvement overther'form shown anddescr bed 1n Letters Patent No. 1,171,314,, issued to me on the 28th'dayof March, 1916. 1

My invention is fully described in the following specification, of whichthe accompanying drawlng forms a part, said draw.- ing being alongltudinal, vertical, section through a gas pressure regulatorconstruct-' ed in accordance with my present invention.

Referring to the drawing, 1 and '2 represent tanks arranged upon a base3 and secured together by means of a strap 4 and in communication witheach other by means of registering passages 5 and 6, these tanks beingcomposed of acid resisting material, such as glass, and the tank 1 isprovided with admin hole 7 normally closed by means of a cork 8 also ofacid resisting material, and with a removable cover 9 having a vent 10therethrough.

The tank 2 has a cover 11 secured thereto, as by bolts 12, and havinga'gas pipe 13 leading to the point of use and controlled by a valve 14in detachable conection with said cover. The cover 11 has a hollow cap15in detachable connection therewith arranged centrally of the cover,and said cover is further provided with a hanger 16 and with a tube 17in detachable connection therewith, said tube being internally threadedfor engagement with an adjustable needle-valve seat 18 and having acover 19 and an inlet port 20 in communication with a gas supply pipe'21held in place by a clamp 22 or in any desired manner.

Pivoted at 23 to the hanger 16 is a lever 24 the shorter arm of which isin pivotal connection with a needle 25 cooperating with the seat 18 toform a gas cut-ofl", the longer arm of said lever having a weight 26slidably adjustable thereon and held in adjusted position by means of ascrew 27 The lever 24 is pivoted at 28 to a carrier 29 in screw-threadedengagement with a vertical rod 30 secured its lower end to a float 31formed of acid-resisting material,

the upper end of'said'rod being contained within the cap 15.

In practice, a quantity of a desired liquid 32 is maintained in thetanks the level of which is controlled by the cork 8, upon removal ofthe cover 9, the liquid in both tanks being normally at the same levelbecause of the passages 5 and6.

, Then the liquid is poured into the tank 1, the cover Q'ha ingbeenremoved for this purpose, said liquid enters the tank 2 and raises theteat 31 and unseats the needlevalve 25, the level of the liquid beinggaged to hold the said valve open under normal conditions. I

If a finer adjustment of the needle-valve 25 is desired, or if it isdesired to re-adjust the same, the cap 15 may be removed and the rod 30may then be rotated to raise or lower the carrier 29 on said rod,thereby.

The apparatus isthus adjustable by means of the cork 8, by means of theweight 26, by

means of the lever carrier 29, and by means of the valve seat 18,thereby insuring any desired degree of control of the gas supply. Whenthe gas pressure is excessive the liquid in the tank 2 is forced intothe tank 1 and the float is permitted to descend correspondingly,thereby partially closing the needle-valve 25 and reducing the gassupply and, when the pressure is reduced, the float again rises andopens the needle-valve. My'invention is very practical and is adevelopment of the form shown in the Letters Patent referred to and,while I contemplate the use of glass for all parts which may be made ofsuch material, and of copper for other parts, I do not limit myself toany specific materials. 1

Having fully described my invention, what I claim as new, and desire tosecure by getters Patent, is c 1. A device of the class described,comprising two tanks connected adjacent their tanks, a supply pipeleading therethrough, a service pipe leading therethrough, a float, avertical rod carried thereby, a lever carrier adjustable on said rod, alever pivoted to said carrier, and a needle-valve in said supply pipe inoperative connection with said lever.

2. A device of the class described, comprising two tanks connectedadjacent their bottoms, an air-tight cover for one of said tanks, asupply pipe leading therethrough, a service pipe leading therethrough, afloat, a screw-threaded rod carried by said float, a carrier in threadedengagement With said rod, a lever pivoted to said carrier, and aneedle-valve in operative connection with said lever for controllingsaid supply pipe.

3. A device of the class described, comprising two tanks connectedadjacent their bottoms, an air-tight cover for one of said tanks, asupply pipe, a service pipe, a float,

a screw-threaded rod carried by said float and extended through saidcover, a removable cap for said rod carried by said cover, a carrier inthreaded engagement with said rod, a lever pivoted to said carrier, anda needle-valve in operative connection with said lever for controllingsaid supplypipe.

4. A device of the class described, com prising two tanks connectedadjacent their bottoms, an air-tight cover for one of said tanks, aservice pipe, a supply pipe, an internally threaded tube through saidcover, a removable cover for the outer end of said tube, a valve seatblock in threaded engagement with the interior of said tube, means forconnecting said tube and supply pipe, a float, a rod carried thereby, alever pivotally carried by said rod, and a needle-valve pivoted to saidlever and arranged to cooperate with said seat block.
